High-voltage switching diodes

Triple high-voltage switching diodes, encapsulated in a SOT457 (SC-74/TSOP6) small Surface-Mounted Device (SMD) plastic package.

Features and benefits

  • High switching speed: trr ≤ 50 ns

  • Low capacitance: Cd ≤ 5 pF

  • Reverse voltage: VR ≤ 200 V

  • Repetitive peak reverse voltage: VRRM ≤ 250 V

  • Repetitive peak forward current: IFRM ≤ 1 A

  • Small SMD plastic package


  • High-voltage switching in surface-mounted circuits

  • Communication

As a Nexperia customer you can order samples via our sales organization.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
